- Reverse Osmosis Desalination
- Sea Salts
- Neritic Zone
- Bathyal Zone
- a Begins at the continental slope and extends to a depth of 4,000 meters.
animals that live there: octopi, sea stars, and brachiopods.
- b A popular method for desalinating ocean water. It includes the use of special membranes that allow water under high pressure to pass through and that block the dissolved salts.
- c The ratio of the mass of a substance to the volume of the substance; commonly expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases.
- d The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.
- e Dissolved solids that make up about 3.5% of the mass of ocean water. These dissolved solids give the ocean its salty taste.
5 Multiple choice questions
- The raising of aquatic plants and animals for human use or consumption.
- Microscopic plants in the ocean that provide food to many of the ocean's organisms.
- The bottom region of oceans and bodies of fresh water.
- Elements that exist in very small amounts.
ex: gold, zinc, and phosphorus.
- The shallow benthic zone that most organisms live in; located on the continental shelves and is populated by organisms such as sea stars, brittle stars, and sea lilies.
5 True/False questions
Distillation → A process of removing salt from ocean water.
Upwelling → A method of desalination where water is frozen. Then the first ice crystals that form do not contain salt. The ice can be removed and melted to obtain fresh water.
Salinity → The ratio of the mass of a substance to the volume of the substance; commonly expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases.
Oceanic Zone → Extends into the deep waters beyond the continental shelf.
Nodules → Organisms that live at the bottom of oceans or bodies of fresh water.
